#credentials_arn ⇒ String

This property is part of quick create. It specifies the credentials
required for the integration, if any. For a Lambda integration,
three options are available. To specify an IAM Role for API Gateway
to assume, use the role's Amazon Resource Name (ARN). To require
that the caller's identity be passed through from the request,
specify arn:aws:iam:::user/. To use resource-based permissions
on supported AWS services, specify null. Currently, this property is
not used for HTTP integrations. If provided, this value replaces the
credentials associated with the quick create integration. Supported
only for HTTP APIs.

#route_key ⇒ String

This property is part of quick create. If not specified, the route
created using quick create is kept. Otherwise, this value replaces
the route key of the quick create route. Additional routes may still
be added after the API is updated. Supported only for HTTP APIs.

#route_selection_expression ⇒ String

The route selection expression for the API. For HTTP APIs, the
routeSelectionExpression must be ${request.method\}
${request.path\}. If not provided, this will be the default for
HTTP APIs. This property is required for WebSocket APIs.

#target ⇒ String

This property is part of quick create. For HTTP integrations,
specify a fully qualified URL. For Lambda integrations, specify a
function ARN. The type of the integration will be HTTP_PROXY or
AWS_PROXY, respectively. The value provided updates the integration
URI and integration type. You can update a quick-created target, but
you can't remove it from an API. Supported only for HTTP APIs.
